Application filed July 22; 1912." Serial in. 710,903..

To all whom it may concern:

Be it known that I, Harmer-H.

citizen-of the United States,and resident of Marcellus, in the county of Onondaga and is a specification. Y

My invention relates to paper feeding and controlling mechanism for 'typewriting machines andits general object is to provide improved mechanism of'the character stated.

More specifically, the. object of my invention is to provide a device which may be readily applied to existing styles of typewriting machines and which is particularly adapted for duplicating items on sheets which overlie each other but are difl'erentially line spaced. For example, in carrying out 'the'embodiment of the invention herein illustrated the object inmindwasjo pro- Vide, first, for filling in the blank spaces of bank 'drafts supplied in continuousform;

ter in the bank draft on an underlying. recordsheet, the duplicated matter being con- :densed;. and, third, for duplicating the amount of the draft, where written in figures, in condensed form on a tally sheet,

which also underlies the draft at-one end and is arranged side by side .with the record sheet aforesaid.

In seeking to obtain the aforesaid results, one of the more specific objects of the invention has been to provide a divided platen, the divisionsfor sections whereof are associated with improved line spacing mechanism that is adapted automatically'to actuate one platen-section at each line spacing operation and to operate the other platen section intermittently.

-Another specific object is to provide for line spacing three separate work sheets preferably in continuous form, by primary line spacing mechanism in combination with secondary paper feeding devices for one of the work sheets, said devices being operative during a. partial cycle of motion to feed the sheet a predetermined distance whlle the other sheets are quiescent, said. devices operating independently of the primary line spacing devices. 0

Another specific object -is'to provide pas per feeding mechanism that is operative first to release the pressure devices cooperative with the platen and next to move the assoclate work sheet a predetermined distance,

these results being accomplished by a'single continuous operation of said paper feeding mechanism.

Another specific object is to provide pa .per feeding mechanism fora plurality of work sheets, the "mechanism for one of said sheets being I-actuated by a rotative hand piece and operat ng during one cycle of movement to release the paper pressure devices coiiperati-ve with the platen and the otherwork sheets, next to feed the first mentioned work sheet a predetermined distance and then to restore the paper pressure devices to operative position.

' Other specific objects will hereinafter appear.

To the above ends my. invention consists in the featurcs of construction, combinations of devices and arrangements of parts hereinafterdescribed and'particularly pointed out a in the claims. second, for'duplicating the typewritten mat- In the accompanying drawings,"Figure 1 is a fragmentary frontv elevation of the platen carrier or carriage of a -Monarch typewriting machine embodying my invention. Fig. 2 is a side elevation partly in 'section of said carriage and its mounting.

Fig. 3 is a sectional view taken on a plane v indicated by the dotted line w-m in Fig. 1 i and looking in the direction of the arrows V at said line. Fig. 4 is a perspective view of a part hereinafter referred to as a pressureroll supporting bracket.

Fig. 5 is a perspective view illustrating the courses taken by the various work sheets as they are-fed through the machine. Fig. 6 is a diagrammatic side view of some of the paper feed-- ing devices in abnormal position. Fig. 7

illustrates some of the parts of Fig. 6 in different relationships. Fig. 8 is a longitudi-v nal sectional view of the divided or seetional platen. Fig. 9 is a fragmentary face "iew of the bank draft sheet or main work sheetand also of the underlying record sheetand the tally strip.

As appears from-Figs. 1 and 2, the top plate 1 of the Monarch machine has secured to it brackets 2 which support grooved guide ways 3 and 4-, the latter coiiper'ating through anti-friction rollers '5 with the grooved rear bar 6 of 'a platen frame, carrier or carriage which further comprises end bars 7 in which is journaled the axle or shaft 8 of the platen.

- the usual finger .piece or key. The usual The platen in the present instance, as best appears from F 8, is a divided one, made up of'two sections, of which'the main or left-hand section 9 comprises a wooden core 10 and a rubber sheath 11. Secured to the left-hand end of the'platen section 9 is a head 12 provided with crown'ratchet teeth 13 and having also a hub 14 which receives a set screw 15 that cooperates with the shaft.

8,. said set screw thus securing the platen?) in rigid relationship with the sha t 8. 1 As appears from Fig. 1 the series of-teeth'on the; ratchet 13 cooperates with a line spacing pawl 16. of the usual description that is controlled by a lever 17 shaped-to provide detent (not shown) for the ratchet 13 is also provided. From Fig. 8, it will be seen that a platen head 18 is secured to the right-hand end of the platen or section 9 by wood screws 19, the outer face 'otsaid head being flush with the end of the sheath 11 and partly underlying said sheath; The head 18 is pro vi-ded with an elongated hub 20 which surrounds and .is supported by the axle 8. The

hub 20 provides a hearing or support for aright-hand or a second platen section 21 which comprises a wooden core 22 and; a rubber sheath Secured to the left-hand end of the core is a head 24 which underlies the sheath 23 and abuts against the outer face of th'e'head 18. Secured by wood screws '25 to the right end of the core 22 is a-platen head 26 provided with a series of peripheral ratchet teeth 27. Abutting the outer face of the head 26 is a-ratchetwheelz28 having peripheral teeth 29 equal in number to the teeth 27. The wheel 28 is of somewhat larger diameter than the head 26 so that the roots of the teeth 27- and 29 terminate at difi'erent distances from the axis of rota-- tio'n, that is, the axle 8. Atleast this is true of the greater number of the teeth 29-; but

"every third notch 29 between'said teeth is cut to agreater depth than its fellows so thatit terminates at the same distance from the axis of rotation as do the notches be tween the teeth 27.' Thevratchet'wheel 28 is provided with a hub 29 which bears on the'outer'end portion of the hub or sleeve 20 and abuts'against the right-hand end bar 7. Across pin30 passes through the hub 29,

'hub'20 and axle 8 and secures-these parts togetherf The construction is" such that both of-theheadsof the platen 9 'areyfixed'to the shaft 8' as are also the ratchets .13 and 29; while the platen section 21 and its ratchet 27 i are normallyrlloose on the'shaft Sand may turn relatiae'l'y'theretoi i litfavill be under.- stood that-tho actuatio'nl' of the line spacing lever 17 operates to turn or line space the.

platen section 9 but never .to 'act iF e the section 21, i 1 1 l Line spacing devices of novel construction are provided for turning or line spacing the platen section 9 at ieach actuation and for intermittently or at every third actuation turning or line spacing the platen section 21. Said novel devices are best shown in Figs; 1,3 and 8 and comprise a lever or arm .31 provided with a hub 32 which bears loosely 'on the hub 29 and is confinedbetween the ratchet wheel 28 and the end bars 7. The free end of the arm 31 terminates, in aiinger piece or key 33 and diametrically opposite thereto is a-lug or projection 34 which car ries a pin 34 over which is hooked a draw spring 35, the rear end of which is anchored to a pin 36 onthe carriage. The spring nor- .mally mamtams. the lug 34 111 engagement with a stop pin 37 projecting laterally inwardfrom the right-hand end bar 7. The 1 arm 31 serves I as a pawl carrier, having pivoted to itat 38 a pawl member 39 whicn depends-from the pivot 38 and'terminates at its lower end in a pawl tooth- 40 which is extended leftward so that it is adapted to cooperate with the ratchet 27 asiwell. as

with the ratchet 29. The pawl 40 operates as agravity paw-l and is prevented from .being swung too far out of operative position, by a stop pin 41 onthe arm 31, said stop pin cooperatingwith the tail portion 42 ofythe member 39. The frame rod or bar 43 which'is secured to;the];'end bars and isor may be of the'usual'paper finger rod, provides a back stop for the arm 31 and so limits the-swinging movement thereof that the pawl 40, cooperates with its ratehets to turn their respective platens only ai-single units line space distance at each actuation, "A roller detent 44 mounted on a 'spring arm 45 which is'secured to the rod 43 cooperates with the ratchet 27 remaintain' it-and the platen section 21' in adjusted .1 5 positions. The construction is such that when the pawl 40 cooperates. with the notches of ordinary, depth in the ratchet 29 I it willbe ,held out of engagement with the ratchet 2 7 because of .the smaller diameter of the latter. This will be plain from Fig.

-3.' Consequently with the partsso relatedan. actuation of tliefinger piece or-key 33 sections turning simultaneously and the effect being'the same as ifthe platen were a single unitary platen instead of a divided platen. It will be seen that I have provided .line spacing devices which operate constantly with the end plates, one nut of each pair at 47 are releasable by devicescomprising. a"

construct-ion being common to the Monarch rod 59, the ends of which are threaded and providesfor readily adjusting the relationsingle piece of slicetmetal and is secured to to advance one platen or platen section and intermittently to advance another platen or, platen' section, the intermittent operation being periodic and in the present instance occurring at every third actuation of the line'- spacing devices.

Cotiperative with the left-hand laten section 9 are feed rollers 46 and'47 o the usual description, said feed rollers being respectively mounted on pairs of springpressed arms 48 and 149. The feed; rollers '46 and rock shaft 50 provided with projections ,51 that cooperate with pins or lugs 520M116. arms 48. The rock shaft 5Q is controlled for releasing purposes by 'a crank arm 53 secured to its left-hand end and connected with a toggle element 54 provided with a tinge-r piece or key 55 and pivotally cons nccted at- 56 with a second tcggleelement 57 pivoted to the platen frame (Fig. 2). By pulling forward the key 55. the shaft 50.is rocked and the rollers 46 and 47 are releasedor moved away'from' the'platen and held in released position asis well understood,'thi s machine. v

The work sheets inthe present; instance are supported-on a frame or carrier (Figs. 1

and 2) comprising end plates 58 and a cross cotiperate with pairs of nuts'GO/associzited the outer face and the other at the inner face of each end plate. Theconstructin ship between the plates. Near their lower ends the end plates are .provided'with hubs 61 which fit over the frame rod 43 and are suitably secured thereto as by .pins 62. Thesepins may be readily removed with a punch'or other tool and then the rod a3 may be detached from the platen frame. The construction enables the supporting frame comprising the end plates 58 to be readily mounted on the platen frame and also to be detached therefrom. To give the supporting'frame additional stability the end plates 58 terminate at the rear in ears 58 which are notched as indicated'at 63 to fit over the rock shaft 50. At the rear of the plates 58 is suitably secured a cross plate or bar 64. Said bar 6a provides a support for a box or container 65 which is preferably made of a the rod 64 as by rivets 6G. The box comprises a bottom, a rear or-back portion and o )osite side ortions these b0111 ureter pl 5 b l ably punched out as shown, to promote lightness. The side portions terminate at 'ends to the plates 58.

their rear upper corners in cars ()7 perforated as indicated at (i8 to receive lugs or projections (39 extending laterally from a} top plate 70, saidto'p plate being hcutat the l downwardprojection at the front of the box. The top plate is thus pivot-ally. supported. on the box and may be readily swung up to give access to the interior thereof. A

fiat spring 73 secured at the rear of'the box coiiperat-es with therear edge of the top 70 to-maintain it down in normal position and alsoto'hold it up when it' has been swung back.- I The upper part of the bar 64.- projects above the bed. or bottom' of the box across its front and provides an abutment corresponding with the projection 72 at the top. It will be understood that the front of.

. the box isopen for the greater part but that closures or abutmentsytt-l; and 72 are providednearthe top and bottom of the opening.- The box65provides a receptacle for the main work. sheet 7-1 which in the present,

inst-anceis in'a' continuous form, being com posed of a. seriesof ba-nkdrafts printed; in blank as illustrated in Fig. 9, each blank at the top andbottoin being joined to its neigh- "bors by a fold, the blanks folding together somewhat like a fan. The arrangement'is clearly shown 1n Fig. 5' and 1t 1s such that a pack of blanks 1s provided, the blanks, however, instead of being separate as is ordi- "nary, each being connected atone long edge with the blank in front of it and at theother longedge with the blank behind it.

By lifting the cover plate 70. suchla pack may'readily'be arranged within the box or holder 65. The partial closures 6% and 72' prevent the pack from being forced byits own elasticity out of the front of the box or from working out of the same. accidentally,- but the opening between these closures is quite wide and readily permits the continuous folded blank to be pulled out as needed, section by's'ecti'on. The free end portion of the sheet 74 is drawn 'down behind the platen and between it and the feed rollers 46 and 4:7. The work sheet 74- extends substair' tially through the full width of the two platen sections and passes up at the front of the'machine behind a guide rod '7 5. Said guide rod extends'llengthwise of the lplatcn inv front of the, same and is secured at its After passing the printing line the work sheet- T-l is controlled by paper feeding devices comprising a rubber faced roller 76, the reduced ends 77 whereof taking bearings in the plates 58; (lotiperative with the roller 76 is a some: what larger rubber faced roller 78' which is fixed to a shaft- 79 that also takes hearings in the "plates 58. The roller 78 is cut away and'red uccd in diameter as indicated at 80 so that for only part of its circumference can it co'ciperate' with the roller 70. The shaft '79 projects outward beyond therighthand plate 58 and receives a cam member 81. said cam nunibcr, as shown in Fig. 1. haying a hub 82 which receives a set screw front to provide a finger piece T-l. and at 83 by which the cam member is secured to git . v Fig. 7 ,thus nearly completing a full'revo1u-.

tion of the' key 87. If the key be advanced said shaft 79. Outside the cam member is arranged a crank arm 84 having ahub 85 secured to the shaft 7 9 by a set screw 86;

The crank arm 84- is providedwith a finger piece or key 87. The periphery of :the cam member 81 cooperates with-a nose 88 on the forward arm of a lever 89 fulcrumed on a' pivot screw 90 secured tothe outer face of theright-hand plate 58. The opposite arm of said lever co-acts 'with an arm 91 secured 'to'the rock. shaft 50. The periphery of the cam member 81. is concentric except where it is notched out as indicated at '81,' and nor-:

mally the nose 88 is seated'in thenotch as shown in Fig. 2. At this time the reduced portion 80 of the roller 78 is 'oppositethe roller 76 so'that said rollers are not in active; cooperation and the work sheet 74 passes loosely upward'between them. If,however, the key 87 be pulled" forward in'the direction of the arrow in Fig. 2'to the'position- Shown inFig. .6, thenose 88 will be forced up on the high part of the periphery of the foam member, thus turning the lever 89 on its fulcrum and causing the lower arm thereof,

acting against the crank arm 91, to rock the shaft 50 and effect the release of the feed rollers46 and 47, the shaft 50 however not being rocked far enough to lock' the toggle 54," 57.. At the same time the working face of the roller '78 will be brought intoco6peration--with the roller 76 so thatif now the rotation of the key 87 be continued the feed rollers 76 and 78 will cooperate ,to advance the work sheetY laround theplaten which, of course; will remain motionless. The ad- Vance of the work sheet will continueuntil the parts reach the position illustrated in to move the parts from the Fig. 7 position back to' the normal position in F ig. '2, -the working face of the roller'78 will separate from the roller '76 and the nose 88 will re-' independent devices or rollers 76 and 78.-

l The work sheet Tl receives impressions directly from the mainribbon which is acted on by the types at the front of the platen.

' In order to transfer the type impressions from the work sheet 74 to underlying sheets,

. a transfer medium is provided, said transfer 'medium being in the form of a contlnuoussheet of very. thin carbon paper92 wh1eh -1s rolled up on the usual paste-board core, said core being frictionallysecured on a supporting roller 93 which may he of metal tubing provided with end or axial portions 94, these portions being seated in inclined" slot-ways 95 formed in the upper ends. ofthe plates 58. The carbon paper'92 is wound on the supporting roller with the carbon faceoutside and is-ledoif rearward from the under side of saidfrolle rl over a guide rod 96 on the supporting frame, and" thence downward behind the platen and around it-and'up at the front side where it is wound on arec'eiving roller 97 having end portions 98 seated in the guideslots .95. The receivingroller is.

supported on the delivery 'rollerand through I the force of gravity the turning movements of the delivery roller are transmitted to the receiving rollerand cause the used carbon to wind automatically thereon}, The carbonpaper 92 is substantially thejwidth of the work-sheet 74 and passes around the platen between it'and said work sheet 74 withthe carbon-face inward toward the platen.

.The supporting. frame comprising the plates 58 provides also a support for the record sheet and the tally strip heretofore referred to, an additional or intermediate plate 99 being also provided for this purpose. 'Said plate 99, as SIELOWII in Fig. 1 is supported "at its upper eudon the rod 59; being clamped to'said rod by nuts 100 which cooperate with threaded portions of the rod at op osite sides ofthe plate 99" and grip said p ate between'them. "The lowerend of the plate'99- is provid'edl with a hub 101 which may be pinned as indicated at 102 to the frame rod 43.- The end plates 58 andthe intermediate plate 99 are provided with slots 103 which are openat the top and extend downward,. inclining slightly rearward, the slot s'registering, of course, with each other. The slot 103 intheleft-hand plate 58 and that in the intermediate plate 99 receive the end portionslOl of a supporting roller 105 for the record sheet 106. Said record sheet passes downward. from itssupport and around the left-handplaten section and the cooperating feedrollers and underlying the carbon sheet 921 Therecord sheet'106 is wound on a receiving roller 107,

"the end portions 107. whereof cooperate re.-

spectively with the slot 103.;in the left-handplate 58 and with the slot in the. intermediate plate 99. The receiving roll 107 rests on the periphery of the rolled up portion 'of-the sheet 106 on the supporting roll 105. and is automatically actuatedthereby' so that as the record sheet is unwound from the delivery roll it is wound on the receiving roll.

The tally -strip 108-is wound on asupporting-ro'llerlOS) having end portions 110' and .1171" whiehengage respectively with thelsliets .ii lq igzinithekplatey 99 and in the right-hand tion 9 only, passing .between said platen sec-.

plate 58, the tally roll being arranged between these last mentioned plates and in reg-.

istcr with the right-hand platen section 21 over which it-is adapted to be'fed. The tally g is drawn downward at the front of its deiiiery roll 109 and over a feed roller 112 which coiiperates with thetop of the platen, being supported on a, Y-shaped bracket 113 best illustrated in Fig. 4. Said bracket is (Fig. 2). The tail of the bracket 113 engages with a pin 115 on the supporting frame. The construction is such that by of saidfeed roll and between it andthe platen section 21 passing around said platen section beneath the right-hand portion of the carbon sheet 92 and upward at the front of theplaten toa' receiving roll 11-6, the ends that the date line on the first blank is oppositethe printing point; while as shown in Fig.1 3 the pawl tooth is opposite one of the shallow notches in the ratche t Wheel 28' immediately below one of the deep notches 29. The operator firstfills in the date on the draft, this being duplicated throughthe carbon sheet 92 on the underlying record,

sheet 106. The key or finger piece 33 is then actuated, line spacing the platen section 9 inaining stationary. The feed rolls 46 and 17 are then released by operating the key and the sheet 74 is drawn upward or advanced by hand independently of the other sheets until the line Pay to the order of is opposite the printing point. .The

feed rollers are then restored and the name is filledlin, being simultaneously transferred through thecarbon sheet to the record :sheet 106; also the amount of the draft in figures is filled in after the dollar sign, transferring through the carbon sheet 92 simultaneously on to the tally strip 108; The platen 9 isagain line spaced by actuating the key 33, thus advancing the sheets 74 and 106 another unit of line space distance and the amount of the draft in wordsis pr nted on; the sheet 7 1- and s'nnultaneously transferred as to the sheet 106. Thereupon the key 33 is preferably of spring metal and is secured to i the top of the rod 13 by a'headed'screw'114 screwing in meat on the screw'114 the pressure of the feed roller 112 may be varied. The tally strip is'draw'n around the front and advancing the sheets 74-, 92 and 106 aunits-distance, the tally strip of course re-- :again operated, but this time the pawl 40 will engage with a deep notch 29 and will J operate to turn both theplaten sections, advancing all the work sheets simultaneously.

This completes j the filling in of the first blank draft which is then ready for the sig naturev of the bank official. The operator next turns the key 87 forward through a complete cycle of rotation, this operation first releasing the feed rollers and then'advancin the main work sheet 74 continuously and in ependently of the platen a' distance such that thedate line on the next succeeding blank form is brought opposite the printing line. Preferably the drafts, are perforated on their'folded'edges as indicated at 74* sons to facilitate their separation from the continuous sheet or strip. As will be unclerstood from what has been sai'd and as appears from Fig} 9 the operations above outlined result in the filling in of the blanks on the draft, the duplicatlon of this matter in condensed form on the underlying work sheet 106 and the printing of the draft totals in condensed form on the tally strip 108. In F 1g. l9,'the record sheet and tally strip are shown advanced far enough to expose the printing.

By the use of my invention as described, the preparation of bank drafts is greatly facilitated; -as heretofore it has been neces sary to employ blanks in book form with stub ends, and eachdraft has required the filling in of the blank drafts, the separate filling in of'the stubswith a pen, and the preparation of a separate slip for the bookkeeper.

Although the present form of my invention is designated for use in the preparation of bank drafts, it is to be understood, of

course, that said invention may be used for various other styles of commercial typewriting for which it may be adopted also that parting from my invention and parts of it may bevused without other parts. What I claim as new and desire to secure by Letters Patent, is
